TE TATES STRING TIP.

Application filed April 18, 1922. Serial No. 554,797.

To all whom it may concern:

Be it known that I, Green. 0. KRUGER, a citizen of the United States, residing at New Salem, in tne county of Morton and State of North Dakota, have invented new and useful Trrnorovenmnts in String Tips, of which the following is a specification.

My present invention has reference to a tip for shoe strings.

My object is to provide a metal tip for shoe strings that shall be of an extremely simple construction which may be cheaply manufactured and which will prevent the tip -from becoming accidentally pulled off of the strings.

A further object is to produce a tip for shoe strings that comprises a bendable metal plate of a suitable length that has one or its edges formed with teeth pointed in the same direction, the said teeth being disposed at an angle with respect to the body of the plate whereby the shoe string may be brought to proper impinging engagement therewith, and thereafter the plate is rolled upon itself around the string, such rolling causing the angle teeth to be flattened against the body, and the direction of the teeth is such that an outward pull on the tip will result only in a tighter engagement of the said teeth with the string.

The drawing which accompanies and forms part of this application, illustrates a satisfactory embodiment of the improvement reduced to practice, and wherein Figure 1 is a perspective view of a tip in accordance with this invention.

Figure 2 is a greatly enlarged transverse sectional view showing the position of the tip when the string is arranged thereover to engage the teeth thereof.

Figure 3 is a similar sectional. view but showing the tip partly bent or wound upon itself to flatten the teeth thereof.

Figure 4: is a view of the complete tip attached to the string.

Figure 5 is a longitudinal sectional view through the improvement.

Figure 6 is a plan view of the blank before the slit portions thereof are upturned to form the teeth.

drawing comprises a substantially rectangir "z lar sheet of bendable metal which is indicated by the numeral 2, Thesheet 2 is provided with V-shaped cut-away portions at one of its edges. The slits of the cutaway portions are arranged parallel and inclined toward one right angle edge of the sheet, and the metal bounded by the said cut-away portions is bent upwardly forming the strip with right angularly arranged teeth 3. It is to be noted that the teeth are all inclined in the same direction. The flat fabric string is arranged over the bendable plate 1 so that the teeth thereof impinge the said strip 1. The metal plate 2 is then rolled or bent upon itself so that the teeth 3 thereof are brought flat against the body of the plate. The metal is further rolled until the same is substantially U-shaped in cross section. The teeth, as stated, are all arranged in the same direction and are so positioned that an outward pull on the plate that constitutes the tip will more effectively embed the said teeth in the strip. In addition to tl is, the rolling of the plate tightly comprcsses the folds of the strip against the folds of the plate.

Having described claim The combination with a flat lacing strip, of a bendable metallic sheet rolled upon itself around the flat lacing strip, a plurality of V-shaped teeth bent upwardly with the base of each V-shaped tooth arranged at a right angle with respect to the metallic sheet the invention, I

and said teeth being disposed through the r strip and inclined toward one end thereof as and for the purpose specified.

In testimony whereof I afiix my signature.
